Vodacom in Breach of Ceded Nashua Mobile Contract

My Nashua Mobile contracts (5) were ceded to Vodacom from December 2014. All went fine till March 2015 when 2 X Contracts did not received their monthly 1 GB data as per the contract with Nashua Mobile. We received it every month since December 2014. On 8 March 2015 I went to the Menlyn Centre and reported the problem. NO ONE FROM VODACOM HAS PHONED ME. I had to follow-up everyday. After one week the one contract was sorted and the data was loaded. On 22 March 2015 I went back to Menlyn Centre. This morning I phoned again. All I get is we will send it to the BACK OFFICE. Everybody is blaming the others of NOT doing their jobs. On Friday - \Lunathi Jos"PROMMISED TO RECTIFY AND CALL ME BACK - NOTHING!! I DEMAND AN ANWSER BEFORE CLOSE OF BUSINESS TODAY!!!"""
